Accelerated processing unitFrom Wikipedia, the free encyclopedia

An accelerated processing unit(APU, also Advanced Processing Unit) is a computer's main processing unit

that includes additional processing capability designed to accelerate one or more types of computations outside of

central processing unit (CPU). This may include a graphics processing unit (GPU) used for general-purpose

computing(GPGPU), a field-programmable gate array (FPGA),or similar specialized processing system.

Variations on the usage of this term include a variation in which the APU is described as a processing device whichintegrates a CPU and an OpenCL compatible GPU on the same die, thus improving data transfer rates between

these components while reducing power consumption by upwards of 50% with current technology over traditiona

architecture.[1]APUs can also include video processing and other application-specific accelerators. Examples

include AMD Accelerated Processing Unit, Cell, Intel HD Graphics, and NVIDIA's Project Denver.

The term accelerated processing unitwas first used in a public context with respect to accelerated computing in

2006,[2]and prior to that in various presentations and business plans written by Joe Landman[3]of Scalable

Informatics.[4]Other uses include Xilinx using the term for an auxiliary processor unit.
